Use of data from the AVIRIS onboard calibrator

Abstract

The AVIRIS onboard calibrator became operational in 1992. This subsystem on the AVIRIS sensor has operated nominally throughout the 1992 and 1993 flight season. This paper describes the data measured by the onboard calibration and the two primary uses of these data. First, the data may be used to optimize the tractability of the calibration of the delivered AVIRIS data to the laboratory radiometric calibration standard. Second, these data may be used to monitor and normalize the inflight radiometric performance of AVIRIS through the flight season.
